Answer:
3 is the correct answer
Step-by-step explanation:
because
Split up the interval [2, 5] into
equally spaced subintervals, then consider the value of
at the right endpoint of each subinterval.
The length of the interval is
, so the length of each subinterval would be
. This means the first rectangle's height would be taken to be
when
, so that the height is
, and its base would have length
. So the area under
over the first subinterval is
.
Continuing in this fashion, the area under
over the
th subinterval is approximated by
, and so the Riemann approximation to the definite integral is
and its value is given exactly by taking
. So the answer is D (and the value of the integral is exactly 39).
Answer:
A. Data
Step-by-step explanation: <em>Data is a term used to describe facts, information or statistics that are collected together in order for it to be used as a reference or for analysis.</em>
An effective data collection is one of the most important aspects in research,experiments or statistics as it helps to guarantee a reliable and effective outcome.
Data collection should be done in such a way that it helps to solve the problem which is being studied or handled.
No x=5 since 5 is the input. The input is always equal to x and the output is always equal to y. So x=5 and y=x+5
